    1985 GS550EF, the saga continues, new petcock, needle/seat...

    Most of you probly remember I was between New Orleans and Laplace near the Bonnett Carre Spillway when my bike shut down suddenly at 60 mph or so.I knew the bike was having fuel problems/electrical problems...but Cliff, Jeep, and others were helpful and I did the coil relay mod, and I thought I was on my way.Next, the needle and seat proved to be a problem.

    I ordered one and got it in, also bought a new petcock, and those things are $75, but I had done three petcock rebuilds over the 16 years I have had this bike, and it never worked out. I got a Briggs&Stratton fuel shut off on it.

    Today, I pulled the carbs off, adjusted the float level on one carb which had been repaired right before I bought the bike. I changed the needle/seat, came home, and then changed the petcock after putting the carbs back on.I tested the petcock to make sure it at least worked in prime...and it did. Bike fired up and and ran fine, then I turned the petcock setting to RUN, and lo and behold, it didnt feed the carbs gas. I got a clear plastic fuel filter, and I could see that it was out of gas.Now, I am stumped.....I rode the bike around and it didnt kill. It started up immediately for me when I cut it off...went back out again and its all good.I


    I just dont understand why it wont run on "RUN".

        Yes its attached and is in good shape. I am going to pull the hose off today and try to suck into the hose enough to see if it gets fuel flowing.

        As for reserve, I havent tried. Sun went down on me.
